It features a multilayer CVD coating system consisting of TiCN, Al2O3, and TiOCN applied via MTCVD process, delivering high wear resistance on steel and moderate wear resistance with toughness on aluminum and non-ferrous materials. The insert has an 80-degree diamond (rhombic) shape, a 0.5-inch inscribed circle, a 0.1875-inch thickness, and a 1\/64-inch (0.0156-inch) corner radius. It is designed for use in turning, facing, and boring operations and is installed by machinists and CNC tooling technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for medium machining operations on steel and cast iron as its primary workpiece materials, with secondary capability on aluminum and non-ferrous alloys. The negative rake angle and negative side clearance geometry are typical of heavy-duty, stable cutting scenarios. With four cutting edges available per insert and compatibility with both clamp and pin holding methods, it fits standard KENLOC-style toolholders used in horizontal and vertical turning centers. It conforms to both ANSI and ISO standards, carrying ISO insert code CNMP120404 and Iso Code CNMP120404K.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer CVD coating: TiCN plus Al2O3 plus TiOCN for extended tool life on steel and cast iron\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CNMP) with negative rake and negative side clearance for rigid, stable cuts\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert, reducing per-edge tooling cost\u003c\/li\u003e\n\u003cli\u003eCompatible with both clamp and pin holding methods for flexible toolholder fitment\u003c\/li\u003e\n\u003cli\u003eMedium chip breaker geometry suited for general turning, facing, and boring applications\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style for consistent, controlled engagement at entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-style toolholders accepting CNMP-style inserts with a 0.5-inch inscribed circle and clamp or pin holding.
